Self-confessed "lighting freak" Simon Ellingworth put together this brilliant LED ring light with an LED camping light, a cheap cover for your smartphone, some velcro, and some scissors. You can see the results in the video above. The whole thing cost him less than £10 (approx $16 USD), although prices may vary where you are. The camping light actually had the ring lighting assembly he wanted inside, so he disconnected it, spray-painted it black (optional) so it fit the look of his phone, and mounted the light to the case with the velcro.

Put the case on the back of your phone, and you have a ring light you can use when you need it and remove when you don't. Plus, it's small enough to fit into any camera bag or backpack. You'll need to adjust your phone's camera settings once you have the light mounted, and he explains the process at his blog.
